Question: What is the biggest curling iron available?
Answer: To my knowledge, the largest curling iron I have seen is the 2 inch Curling Iron. The 2 inch curling iron is very big. It makes large large large loose waves if you have long hair. The 2 inch curling iron may not work in your hair if it is too short. I have only seen a few brands make the 2 inch curling iron. Hot Tools, I believe is the best one. Check it out here.
